Test Case taDOM3+/25-taDOM3+-29-CH

taDOM3+ Lock Requests of executed Operation prependChild(contextElementNode, childType, childValue) returns Node

The prependChild operation is executed on the context element node CO and prepends a new child to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.

Behavior specified with base operations:

readCO
modifyCOFCE
modifyFCPSE

Read Set = CO , Write Set = COFCE FCPSE

LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:-]
LockRequest[node=FC,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation insertAfter(contextNode, siblingType, siblingValue) executed on node CH

The insertAfter operation is executed on the context element node CO and inserts a new next sibling node after the context node CO. There already exists a next sibling and the inserted new sibling node is returned.

Bahavior specified with base operations:

readCO
modifyCONSE
modifyNSPSE

Read and write sets for execution on CH:

Read Set = CH , Write Set = CHNSE

LockRequest[node=CO,lock:NR,PSE:-,NSE:EX,FCE:-,LCE:-] on CH
LockRequest[node=NS,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-] on CH
